Title: Composite bearing
Inventor: MATSUDA RYUICHI
IPC: F16C32/00
Filed: 1986-04-28
Abstract: PURPOSE:To obtain high dimensional precision by applying support force of a squeeze air membrane and repulsive force of a permanent magnet to a composite bearing so as to support the composite bearing with non-contact with the movable part. CONSTITUTION:When alternating voltage is applied on each of piezoelectric materials 21 and 22 of each vibrator 11 and 12 through each of lead wires 34 and 35 so as to make vibrating faces 13 and 14 vibrate respectively, squeeze air membrane force is produced within micro-clearances 30 and 31 between these vibrating faces 13 and 14 and a movable part 19. Thereby, the movable part 19 is supported with non-contact in the thrust direction. Further, the movable part 19 is supported with non-contact in the radial direction by the aid of repulsive force between permanent magnets 16 and 20. Accordingly, the vibrating faces 13 and 14 for forming a squeeze air membrane and faces 32 and 33 opposed to the movable part 19 are flat, and high work precision can easily be obtained.

IPC: B60S1/02
Filed: 1983-06-02
Abstract: PURPOSE:To heighten the capacity of a defroster in time of engine starting, by controlling a heating wire for the defroster on a window pane so as to increase its heating value when engine temperature is below the setting value. CONSTITUTION:In time of engine starting, since water temperature inside a cooling water pipe B is low, a switch 6 is being turned on by the detection value of a temperature sensor 5 whereby a heating wire 1 and a reinforced heating wire 1a both are energized with current and thus heated. With this constitution, frost or dew clinging to a rear window is powerfully melted and eliminated into vaporization. Between whiles, when water temperature inside the cooling water pipe B is low, and engine is in warm-up running at high revolution so that power generating capacity in a generator is ample enough. When the water temperature goes up, the switch 6 is turned off, making no electric current flow in the reinforced heating wire 1a at all.

Inventor: TAKEGAMI TAKESHI
IPC: H01J1/316
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To suitably set the emitting position of electron near the support member of an electron device by setting the space of two electron emitting elements mutually adjacent with the support member between larger than the space of two electron emitting elements mutually adjacent without the support member. SOLUTION: When the distances D1, D2, D3, D4, D5 from a spacer 1020 to each element are properly regulated, respectively, spot intervals Q1, Q2, Q3, Q4, Q5 on a face plate 1017 of the respective electrons emitted from the elements are substantially constant. Namely, the distance from the position in which the electron emitting position is vertically projected on a substrate 1011 to the position for providing the element is set according to the distance from the spacer 1020 to the element. Particularly, this distance is set so that the element closer to the spacer 1020 has the larger distance, whereby the emitting position can be approached to a substantially uniform arrangement. Thus, when this device is applied to an image forming device, an image free from the image distortion or luminance reduction by charge of the spacer 1020 can be formed.

IPC: H01L21/31
Filed: 1988-04-22
Abstract: PURPOSE:To form a flattened insulating film by a method wherein a substrate being heated is sputtered to form a reflow glass while discharging sputtering gas. CONSTITUTION:A target which selects the composition out of the compositions such as PbO; 30-70wt.%Pb, SiO2: 50-20wt.% Si, P2O5: 4-8wt.% P conforming to arbitrary flow temperature is used. The substrate heating temperature in a sputtering device with even heat kept on is set up at the flowing temperature of PbSG. Then, the substrate to form reflow glass is carried to a sputtering chamber while the heating temperature of this substrate is kept at the set up flowing temperature. In such a state, PbO-SiO2-P2O5 target is sputtered to be deposited on the substrate. At this time, the substrate temperature being set up at the flow temperature, the PbSG deposited on the substrate starts to flow simultaneously to form a flattened PbSG film on the spot. Through these procedures, a flattened insulating film in excellent quality containing little gas and producing no bubbles at all can be formed in only one process.

Title: Automatic focus adjuster
Inventor: KITAMURA YOSHINORI
IPC: G02B7/28
Filed: 1982-06-09
Abstract: PURPOSE:To obtain an automatic focus adjuster which always operates stably, by changing the amount of the change of a device, which gives out-of-focus to an image according to the state of the diaphragm of a lens, in order to reduce the change of the gain of a feed back circuit. CONSTITUTION:A comparison circuit 12 compares reference electric potential with image wave detecting output electric potential of a rectification circuit 11 and performs negative feed back so that the wave detecting output electric potential becomes the same as the reference electric potential. A diaphragm driving circuit 13 changes the amount of change of a focus adjuster of a lens with the output electric potential of the circuit 12 and changes the diaphragm of a lens 1 by controlling the gain of a gain controlling circuit 10. If the diaphragm of the lens is in open state or near the open state, the gain of the circuit 10 becomes smaller, and, if the diaphragm of the lens is contracted, the gain of the circuit 10 becomes larger in order to reduce the amount of change of an image formed on the light receiving surface of an image pickup tube at the reference frequency of the scumble of the image. As the result, an automatic focus adjuster operates stably in any diaphragm condition.
